Ok, I have been searching the internet for days for an answer to this problem.
Here's a list of the essential components I have for my home theater:
-Sony Vaio Media Center (Standard computer really with Media Center 2005 edition) with Sony BWU-100A Blu-Ray Disc Rewritable Drive (I upgraded to this drive)
-Asus 7600GT Video card with HDCP over HDMI port
-Cyberlink PowerDVD Ultra BD Edition 7.2
-Yamaha HTR-5990 receiver
-Mitsubishi WD-65731 1080p DLP TV
Ok the Vaio computer has PowerDVD blu-ray edition installed along with the blu-ray drive. The video card is connected to the receiver through the hdmi port on the asus video card. Where the receiver is then connected to one of the hdmi ports on the back of the tv.
According to the cyberlink advisor program the HDMI path is hdcp protected. However, the video card output can only be set to 1080i or lower. I believe this is due to the yamaha receiver only being able to switch 1080i signals.
Since, 1080p is supported by both blu-ray and hddvd I've been trying to get a native 1080p signal from the htpc. Here's the problem...
When I connect the HDMI cable directly from the htpc video card to the mitsubishi tv, I can send a native 1080p signal to the tv. However, according to the cyberlink advisor the HDMI signal is not HDCP protected.
So in short, I have an HDCP protected signal over HDMI coming from the computer to the receiver to the tv at 1080i. When I connect the computer directly to the tv for a 1080p signal the HDMI signal is no longer protected by HDCP.
I've been driving myself crazy trying to figure this one out, if anyone has any advice it would be greatly appreciated.
p.s. I had the hyperlinks embedded but the avsforum made me remove them since this is my first post.
